MILK-CAN.

I '0 all whom, it may concern Be it known that I, CARL ZWERMANN, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Milk-Cans, of which the following is a specification.

This invention relates to improvements in The objects of this invention are: First, to provide an improved construction of milk can for shipping purposes in which the body of the can is coated with enamel and the can itself protected from injury, which injuries ordinarily in a shipping can would destroy the enamel. Second, to provide a construction of milk can which will be entirely sanitary. Third, to provide a milk can in which the milk can be effectively cooled and kept cool. Fourth, to provide an improved construction of bottom for a jacketed milk can. Fifth, to provide an proved construction of top for a milk can of this kind. Sixth, to provide an improved which can be effecconstruction of cover, tively clamped in place,and avoid slopplng or .other contents of the can, for the can is effective for various purposes; Seventh, to provide an improvedconstruction of outer'jacket for protecting the enameled interior of a milk can.

Still further objects relating to'detailsof construction will definitely appear from the detailed description to follow. a

I accomplish: the objects of my invention by the devices and means described in the following specificatiom The. invention is clearly defined and pointed out in the claims.

A structure, which is a preferred embodiment of my invention, is fullyillustrated in the accompanying drawing, forminga part of this specification, in which:

Figure 1. is a detail elevation view, par- .of a. milk' can embodying, the features of myinvention, showing deli nitely the arrangement of the parts. Fig; 2 is a verticalxsectional elevation view, showing the method of assemblingand uniting the parts. Fig. 3 is a transverse detail sectional view. on a line correspondin to line showing the metho of supporting the interior casing by the spring fingers. Fig, 4 is a detail vertical sectional view of one of the spring-fingers, and ad jacent parts showing the method of'its con tact and [support for the inner enameled lining.

In the drawing, similar numerals of reference refer to similar parts throughout the several vlewsr Considering the munloered parts of the drawing, the lower portion lot the inner case of the can is suitably rounded and connected to the upper portion 2, which terminates in a suitable breast 3, which extends upwardly into a neck l and receives the upper heavy ring portion 5. The parts 1 and 2 are joined. together by a suitable welded joint 6, and are coated on the outside by. a 1 a layer of enamel 7 and on the inside wit layer of enamel 8.

piece of compoa-sitiou cork-board or annular insulator 9, wlnch entirely surrounds and protects the same. An outer acket 10 is suitably separated from "the inner coated casing, and is provided with stiffening,

11. The bottom 12 the insulator-layer the Inner casing and is suitable rivets l5.-. are suitably secured to the The bottom of the can is supported by a a outer jacket, and the upper portion 17 of the can is flanged outwardly at 18 and termi nates in. a suitable beaded rim 1.) at its upper edge,

A cover 20 fits tends downwardly, forming tacle 21 within the can, a Hat shouldered portion 22 which fits the upper portion of the heavy ring 5, to which the necks of the inner casing and the outer. can are suitably secured, the same being machined off to form a flat surface fora joint at that point. and is flanged upwardly and outwardly at 23 and terminates in a head 24. The cover is secured in place by a spring clamp25, which is connected by a seal 26 to a loop 27 on the said cover 20. An inner" cover" 28, provided with a handle 29, closes the ice receptacle 21.

Spring fingers 30ers secured to the acket and extend obliquely inwardly into contact; with the inner casing of the can,- the enamel an ice recepbeingprotected from in ury by an inter posed leather cushion 31, which cushions the spring and :prevents abrading of the cm amel.

I desire'to stateithat the structure of my improved can can be considerably modified and- 1S provided with within the same, and exj The 'cover is flat at 22 i without departing from my invention. I

' desire, however, to claim the specific form I metal exterior ring at in which I have shown it, and also to claim the structure broadly.

The structure will lend itself to use with any suitable milk can cover. The one that I have here provided is adapted for hot weather shipment of milk modities. The structure would be very well protected and be a very good refrigerating can, even though the interior was not enameled. I have provided this structure as especially adapted and intended to protect the enameled inner casing, which is ex-- tremelynecessary in a shipping can, else the blows to which it will be subjected will crackand injure the enamel and its effectiveness be entirely destroyed.

Having thus described my invention, what I claim as new anddes'ire to ,seoure'by Letters Patent is:

1. In a milk can, an interior casing with rounded corners, with suitable enameled nally to the said neck; andwa cover with tion therefrom, I

same; a cushion insulator bottom surroundsuitable shoulder conformed to theupper surface of the said ring substantially as described and for the purposespecified.

2. In a milkcan, an interior casing with rounded corners, with suitable enameled coating; an exterior jacket in" spaced relasuitably ribbed to stiffen the ing and supporting the bottom of the inner jacket and cushioning the same; a sheet metal exterior bottom shell conformed to the said insulator bottom and flanged around the lower edge of the said jacket and suitably joined thereto; a heavy metallic ring at the neck of said can for supporting the upper edge of the enameled inner casing, to which the jacket is secured, the whole dressed to a smooth joint at the top; suitable sheet metal parts secured externally to the said neck; and a cover with suitable shoulder conformed to the upper surface of or similar comsheet metal exterior bot-tom thesaid ring substantially as described and for the purpose specified.

- 31 In a rounded corners, with suitable enameled coating} an exterior jacket in spaced relation therefrom, suitably ribbed to-stiffen the same; a cushion insulator bottom surrounding and supporting'the bottom of the inner jacket and cushioning the same; a sheet metal, exterior bottom shell conformed to the'said insulator bottom and flanged around the lower edge of the said jacket and suitably joined thereto; a heavy metallic ring at the neck of said can for supporting the upper edge' of the enameled inner casing, to

which the jacket is secured, the whole -dressed to a smooth joint at the top; and

milk can, an interior casing with.

suitable sheet metal parts secured externally to the said neck; substantially as described and'for the purpose specified.

4'. In a milk can, an interior casing with rounded corners, with suitable enameled coating; an exterior-jacket in spaced relation therefrom; a cushion insulator bottom surrounding and supporting the bottom of the inner jacket and cushioning the same; a shell conformed to the said insulator bottom and flanged I around the lower edge of the said jacket and suitably joined thereto; a heavy metallic ring at the neck the upper edge of the enameled inner casing, to which the jacket is secured, the whole dressed to a smooth joint at the top; suitable sheet metal .parts secured externally to the said neck and a cover with suitable shoulder conformed to theupper surface of the said ring substantially asdescribed and forthe purpose specified.

5. In a milk can,'aninterior casing with rounded corners, with suitable enameled coating; an exterior jacket in spaced relation therefrom; a heavy metallic ring at the neck of said can for supporting the upl of said can for supporting shoulder conformed to the upper surface of thersaid ring substantially as described and for the purpose specified. 4 In witness whereof, I have hereunto set my hand and seal in the presence of twowitnesses.
